Why this is important is we can then see how toll ways, off ramps, signals and other things impede traffic flow and the flow of goods and services to markets. How trains and boats and containers interact. How people on buses, trolleys, trains, aircraft, hydro craft, ferries, motorcycles, taxi cabs, limos and passenger cars move. How the system works together with Air, rail, Water and road travel no matter what the type of transportation used. This is like a giant train set you never have to build, can change at will. A holographic display, which can zoom in, zoom out, replay, record sessions, back up. Move to another state, county, city streets, just like a Google Map, but in 3D and 4D. $D in that you can see subways underneath tunnels and double-decker freeways such as in Seattle, SF, San Antonio. You can see the NY subways, Bart trains under the bay, the Baltimore Tunnel, you see, why we need this? And since we have the technology, we can run the system to perfection, increasing our nations productivity, decreasing traffic jams, enhancing response time to first responders. We can run our a Net-Centric Battlefield, not delivering bombs to the enemy, but delivering products, people, packages, goods and services to the masses. Efficiency in the flow of transportation is a vital part to a healthy economy.

Someone like Snow the treasury secretary, a former Railroad man, might want to have a similar device for money flows and markets and since he is very valuable to the administration than that of merely a treasury secretary, he should be given the assignment of working with the DOT to develop systems to streamline the infrastructure, which will lower prices to consumers through efficiencies and raise profits for transportation companies which will increase flow and help us with the future inflationary period by lowering costs through efficiencies and it also saves fuel and of value to our dependence on foreign oil and the Energy Issues which are vital to the country. Can you see the potential here?
